Effects of the Inclusion of Exercises "Core Stability" in the Treatment of Inpatient Physiotherapy to Improve Balance in Post-stroke Patients Sitting in Subacute Phase. Randomized Clinical Trial.

The stroke as cerebrovascular disease is the leading cause of permanent neurological disability and the third death in the Western world. Their affected often have motor and sensory disturbances in the form of hemiparesis with a possible influence on the balance be altered trunk muscles, important components of postural control. The treatment of stroke, covers a wide range of different strategies and approaches physiotherapy, including, specific exercises on the trunk called "core stability", performed by the patient with the help and supervision of a physiotherapist specializing in neurology, that are based on coordination, motor and proprioceptive work, especially the lumbar-pelvic. The effectiveness of these last years has been demonstrated empirically, but until now there is no sufficient evidence of the effects of these exercises on sitting balance in respect, and standing up in the subacute phase post-stroke patients. To prove the evidence raises a randomized, multicenter, blinded and where the evaluator will not participate in the analysis and processing is done by intention to treat. Patients will be divided into two groups: control (usual physiotherapy center made ) and experimental (made also 15 minutes workout "core stability"). The intervention will have a frequency of 5 days a week for 5 weeks and up to 12 weeks. The expected effect is that the experimental group patients develop better postural control at the trunk and this influences the balance in sitting, standing and walking.
